Why You'll Love It:

Easy, everyday essential.

Eye-Catching Design

Why It's Different

Most companies that claim to have cooling, sweat-wicking bedding only attempt to manage temperature once you've already become uncomfortable. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a proactive, not reactive, approach to temperature regulation. Outlast® technology regulates heat to stop moisture from developing in the first place, instead of attempting to wick away sweat that has already developed.

Not too hot…not too cool…just right.
